    Default HELPPPPPP Java Program With JButtons and JFrames

    Okay so I need to build a program that has 3 panels and a group object, one of the panels will contain two other panels, a top panel that display's the group's name and average gpa, and a center panel that contains 4 buttons which display each of the 4 students of the group including their name and individual GPA.


    I have a feeling I'm going wrong somewhere with the supers and that's why I keep getting errors when I try to pass over st1.getInfo() to the CenterPanel class.



    I need a total of 7 classes:
    app
    mainframe
    controlpanel
    toppanel
    centerpanel
    group
    student

    Here's what I have for each class:

    app.java:


    public class app
    {

    public static void main(String args[])
    {
    MainFrame mjf = new MainFrame();
    }

    }

    CenterPanel.java:


    import java.awt.*;
    import javax.swing.*;

    public class CenterPanel extends JPanel {

    static JButton jb1, jb2, jb3, jb4;

    public CenterPanel() {

    super();
    GridLayout grid = new GridLayout(4, 1);
    setLayout(grid);
    setBackground(Color.pink);
    student st1 = new student("Mike","Myers");
    jb1 = new JButton(st1.getInfo());
    add(jb1);
    jb2 = new JButton();
    add(jb2);
    jb3 = new JButton();
    add(jb3);
    jb4 = new JButton();
    add(jb4);
    }

    public JButton getJb1() {
    return jb1;
    }

    public void setJb1(JButton jb1) {
    this.jb1 = jb1;
    }

    public JButton getJb2() {
    return jb2;
    }

    public void setJb2(JButton jb2) {
    this.jb2 = jb2;
    }

    public JButton getJb3() {
    return jb3;
    }

    public void setJb3(JButton jb3) {
    this.jb3 = jb3;
    }

    public JButton getJb4() {
    return jb4;
    }

    public void setJb4(JButton jb4) {
    this.jb4 = jb4;
    }
    }

    ControlPanel.java


    import java.awt.*;
    import javax.swing.*;

    public class ControlPanel extends JPanel
    {

    CenterPanel cp;
    TopPanel tp1;

    public ControlPanel()
    {
    super();
    BorderLayout border = new BorderLayout();
    setLayout(border);
    setBackground(Color.gray);
    cp = new CenterPanel();
    tp1 = new TopPanel();
    add(tp1, "North");
    add(cp, "Center");
    }

    }

    group.java:
    import java.util.*;
    import java.awt.*;
    import javax.swing.*;

    public class group extends TopPanel {

    String groupName;
    ArrayList<student> studentgrouplist;

    public group(String groupName1) {
    groupName = groupName1;
    studentgrouplist = new ArrayList<>();
    }

    public String groupList() {
    String info = "";
    for (int i = 0; i < studentgrouplist.size(); i++) {
    this.getStudentgrouplist().get(i);
    student temp = this.getStudentgrouplist().get(i);
    info = info + "\n" + temp.getFirstName() + " " + temp.getLastName() + ": " + temp.getRandomGPA();
    }
    return getGroupName() + info;
    }

    public double groupAvg() {
    double total = 0;
    for (int i = 0; i < studentgrouplist.size(); i++) {
    total = total + this.getStudentgrouplist().get(i).getRandomGPA();
    }
    return total / studentgrouplist.size();
    }

    public String getGroupName() {
    return groupName;
    }

    public void setGroupName(String groupName) {
    this.groupName = groupName;
    }

    public ArrayList<student> getStudentgrouplist() {
    return studentgrouplist;
    }

    public void setStudentgroup(ArrayList<student> studentgrouplist) {
    this.studentgrouplist = studentgrouplist;
    }
    }

    mainframe.java:

    import java.awt.*;
    import javax.swing.*;

    public class MainFrame extends JFrame
    {

    ControlPanel mjp;

    public MainFrame()
    {
    super("Assignment 05 Starter");
    mjp = new ControlPanel();
    getContentPane().add(mjp, "Center");
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setSize(1200, 500);
    setVisible(true);
    }
    }

    student.java:
    import java.awt.*;
    import javax.swing.*;

    public class student extends CenterPanel {

    private static student st1;
    private static student st4;
    private static student st3;
    private static student st2;
    String firstName;
    String lastName;
    double randomGPA;

    public student(String pFirstName, String pLastName){
    super();
    firstName = pFirstName;
    lastName = pLastName;
    double gpa = Math.random();
    randomGPA = gpa * 5.0;

    student st1 = new student("Mike","Myers");
    student st2 = new student("Test","Blah");
    student st3 = new student("Brad","Long");
    student st4 = new student("Mitch","Best");
    }

    public void setGetInfo(String firstName, String lastName) {
    this.getJb1();
    }

    public String getInfo() {
    return this.getInfo();
    }
    public String getFirstName() {
    return firstName;
    }

    public void setFirstName(String firstName) {
    this.firstName = firstName;
    }

    public String getLastName() {
    return lastName;
    }

    public void setLastName(String lastName) {
    this.lastName = lastName;
    }

    public double getRandomGPA() {
    return randomGPA;
    }

    public void setRandomGPA(double randomGPA) {
    this.randomGPA = randomGPA;
    }

    }

    TopPanel.java:


    import java.awt.*;
    import javax.swing.*;

    public class TopPanel extends JPanel
    {

    JButton jb1, jb2, jb3, jb4;

    public TopPanel(){

    super();
    setBackground(Color.gray);
    jb1 = new JButton();
    ImageIcon psu = new ImageIcon("images/psu.jpg");
    jb1.setIcon(psu);
    jb1.setBackground(Color.white);
    add(jb1);
    jb2 = new JButton("Group Name Goes Here");
    jb2.setBackground(Color.white);
    add(jb2);
    jb3 = new JButton("Group Average GPA is");
    jb3.setBackground(Color.white);
    add(jb3);

    jb4.setBackground(Color.white);
    add(jb4);
